Country’s assorted lotteries taking in millions (5-5)
I believe the answer is:
timor-leste
'country's' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'assorted lotteries taking in millions' is the wordplay.
'assorted' is an anagram indicator.
'taking in' means one lot of letters goes inside another.
'millions' becomes 'm' (abbreviation).
'lotteries' is an anagram of 'tiorleste'.
'tiorleste' placed around 'm' is 'TIMOR-LESTE'.
Can you help me to learn more?
(Another definition for timor-leste that I've seen is " Asian State".)
